enable normal SSI for output of mod_perl script

[Surat Singh Bhati]

Hi,

I want to filter/process some files using my own 
handler as:

<Location /foo>
   SetHandler      perl-script
   PerlHandler     Apache::Myprocessing
</Location>

Now, beofre sending the output of above handler to browser, I want
to process it as normal server-parsed (i. e. apache should search for
the SSI tags like <!--#exec cgi="/abc.cgi"--> , process them, and 
serve the final output to the browser.

Please suggest me how to configure Apache and mod_perl for it.

Thanks and Regards,
